For the fourth year in a row, health insurers Anthem and ConnectiCare will be asked to explain in a public forum the reasons for their requested premium increases.

The Connecticut Insurance Department announced the subjects of the Sept. 5 hearing on Wednesday. It will be held at 10 a.m. in CID's offices at 153 Market St. in Hartford.

The hearing will focus specifically on Anthem's and ConnectiCare Benefits' rate requests for individual health policies sold through the state's Affordable Care Act exchange, Access Health CT, which cover more than 100,000 people.

In July, Anthem filed its request for a 9.1 percent average rate hike for those plans next year, while ConnectiCare is asking for a 13 percent average rate increase.
